Dangerous Heat Wave To Grip Area This Weekend; Heat Index Values As High As 115F

Temperatures are on the rise as we move into the hottest few weeks of the year on average. Daily highs reaching into the 90s to low 100s combined with 50-70% humidity will result in heat index values well into the 100s and 110s. Although Friday and Saturday will be the hottest days of the stretch, Thursday and Sunday will still feature heat indexes only a 5-10 degrees cooler. It is important to take precautions to keep you and your loved ones safe during a heat wave of this intensity. Below are some key points from NOAA.

The heat wave will come to an end Monday, as a cold front likely accompanied by thunderstorms will move through, leaving behind below average temperatures next week. But for now, the worst it still yet to come.

Josh has been passionate about weather as long as his memory dates! From watching the Weather Channel at age 7, to making hand-drawn hurricane maps at age 11, starting his first weather site at 13, and founding PWA at 15 and forecasting for the state for the past 9 years, Josh's interest in weather has never dwindled! As difficult as it is, he greatly enjoys forecasting for Pennsylvania due to its countless microclimates. The state is an East Coast severe weather hotspot and nearly always home to the rain/snow line during winter storms!
